In another embodiment, the processing unit may also only erase the user data matching the specific file type according to the third remote control command, and the specific file type may be set by the user through the service website. For example, the processing unit 125 only erases the conversation logs and short messages stored in the internal storage unit 123, but keeps data of other file types and the configuration values set for each function.
  • the user may decide whether to backup the data stored in the mobile device 120 to the server 110', erase only the data stored in the external storage unit 127 of the mobile device 120, or simultaneously erase the data stored in the external storage unit 127 and the internal storage unit 123 through the service website. Accordingly, the user can prevent a finder from freely accessing the data content stored in the mobile device 120 by the user.
  • the server 110' may synchronize the data stored in the backup database 310 with the internal storage unit 123 and/or the external storage unit 127 of the mobile device 120.
